TYPO3 Core

When using the new fluid_styled_content I guess you can uninstall css_styled_content, as all you need should be handled by fluid_styled_content. But the elements of fluid_styled_content aren't displayed in the NewContentElementWizard. I compared the two extensions and found the following snippet in the ext_localconf.php of css_styled_content:

// Include new content elements to modWizards
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPageTSConfig('<INCLUDE_TYPOSCRIPT: source="FILE:EXT:css_styled_content/Configuration/PageTSconfig/NewContentElementWizard.ts">');

This part is missing in fluid_styled_content. Should be added there too (with changed file path of course).
